ABSTRACT

Objective:

Compare the clinical effectiveness of custom thermoformed occlusal splints (OS) alongside behavioral and self-care therapy (BST) in the management of myalgia of the masticatory muscles. Material and

methods:

A controlled clinical trial was conducted with a total of 46 subjects with a diagnosis of myalgia according to the Diagnostic Criteria for Temporomandibular Disorders (DC/TMD). All subjects were treated with BST at the beginning of the study and were then randomized into four groups behavioral and self-care control group; Thermoformed Tough-elastic splint group; Thermoformed Soft-elastic splint group, and non-occlusive splint group. Follow-ups were carried out at 2, 6, and 10 weeks, where it was evaluated pain in the masticatory muscles, mandibular range of motion, mandibular functional limitation, and occlusal discomfort. Data were analyzed with Doornik and Hansen, Shapiro­Wilk, and ANOVA at p=0.05.

Results:

All the variables showed significant improvement (p<0.05) from the first follow-up and were maintained later. BST control group, as well as groups with BST associated with OS, were able to reduce pain and increase the mandibular range of motion without significant differences between them (p>0.05), while the Thermoformed Tough-elastic splint was the most efficient in terms of the mandibular functional limitation. The occlusal discomfort decreased over time, but without statistically significant differences in terms of time and design of OS.

Conclusion:

The addition of thermoformed OS to behavioral and self-care therapy does not have a significant impact on myalgia of the masticatory muscles. (AU)
RESUMO

Objetivo:

Comparar a eficácia clínica das Placas Oclusais (PO) termoplásticas personalizadas associadas à Terapia Cognitiva Comportamental (TCC) na condução da mialgia dos músculos mastigatórios. Material e

Métodos:

Foi realizado um ensaio clínico controlado randomizado com um total de 46 participantes com um diagnóstico de mialgia de acordo com os Critérios de Diagnóstico das Desordens Temporomandibulares (DC/TMD). Todos os participantes foram tratados com a TCC, no início do estudo, e foram, depois, randomizados em quatro grupos grupo controle Terapia Congnitivo Comportamental; grupo de placa termoplástica dura-soft, grupo de placa termoplástica soft, e grupo de placa sem cobertura oclusal. Foram realizados controles com 2, 6, e 10 semanas, onde foi avaliado dor nos músculos mastigatórios, amplitude de movimento mandibular, limitação funcional mandibular, e desconforto oclusal. Os dados foram analisados com Doornik e Hansen, Shapiro-Wilk, e ANOVA a p=0,05.

Resultados:

Todas as variáveis mostraram melhora significativa (p<0,05) desde o primeiro controle e se mantiveram posteriormente. O grupo de controlo da TCC, bem como os grupos com TCC associada a PO, foram capazes de reduzir a dor e aumentar a amplitude de movimento mandibular sem diferenças significativas entre eles (p>0,05), enquanto que, a placa termoplástica dura-soft, foi a mais eficiente em termos da limitação mandibular funcional. O desconforto oclusal diminuiu ao longo do tempo, mas, sem diferenças estatisticamente significativas em termos de tempo e design da PO.

Conclusão:

A inclusão da Terapia Cognitivo Comportamental à PO termoplástica não tem um impacto significativo na mialgia dos músculos mastigatórios.(AU)
